The game itself has an interesting “acrobatic” system and a helpful set of items. This hack gives a new challenge and maybe even a look at the game at a different angle - where thinking and tactics may prove more useful than reaction (especially on the hardest difficulty). The idea is to force player to use Willy’s whole arsenal of moves and equipment in the most efficient way according to the situation.

• There are 5-, 3- and 1-HitPoint modes available in the main menu. After choosing a “difficulty level” you can either Start a new game or Select entering a password with corresponding buttons;
• The in-game combination of “Start,A,A,A” works as always, returning you to the “Choose level” screen (if you choose the same level after that - you’ll start from a checkpoint);
• Starting number of lives is increased and it is 5(+1) in the maingame and 15(+1) in the post-game bonus level;
• When HP is full, “hearts” will give you money instead;
• All arrow-cursors replaced with “cat paws”)
• The game now fully translated to English.
